A metal oxide / carbon nanotube nanocomposite and its preparation method

The present invention improves, high rate characteristics and the metal of the oxide to the carbon nanotube surface chemical nano composite as by a smooth electron supplied to the metal of the oxide active material is related to a metal in the oxide / carbon nanotube nanocomposite and its preparation method . The present invention also has an advantage capable of easily controlling the film thickness on, the nanocomposite by adjusting the metal oxide amount. Nanocomposites of the present invention exhibits an excellent high rate characteristic by improving the electrical conductivity of the electrode material can be applied to energy storage material, such as an electric vehicle battery, a lithium ion capacitor.
